To otZZ whom it may concern,-

Be it known that I, FRANK l'lARPER, a. citizen of the United States,residing at J sckson, in the county of Jackson and State of Ohio, haveinvented certain new and. useful Imrovolnents in Cooking-Stoves, ,ofwhich the on improved construction of cooking stove designed to cook bymeans of either gas or assembled ports will be compactly arranged ande'llicient in operation for all the various uses of which a device of,this character is or). able. I

or a full description of-the invention and the merits thereof and alsoto acquire a knowledge of the details of construction of the-niesns forcll'ectiug the result, reference is to be had to the followingdescription and soicompzrnying drz-rwings, in which:

Figure 1 is it top plan view of my improved combination stove, port ofthe top thcrooi' Fig. 2 is :1 vertical longitudinnl sectional view.

Correspomling and like parts are referred to in tl following descriptionand indicated in all the views of the drawings by like reforfront andcool; wells or castings}; and 4.

upon shelf or plaic 6. The fire box in the resent embodiment of myinvention is coated (it the extreme left of the body proper ofjzhestove, as shown.

My improved cocking stove also embodies sf closet or receptacle 7 whichis secured by rivets or the like to the body of the stove in a suspendedrelation and which is intended to contain a removable oven 8 which inoperative relation is supported on top of the receptacle 7. in additionto this removable oven, the stove embodies c stationary oven 9 which inthe present instance is located at the therein in a spaced relationli'om the walls of if e stove body so as to provide a line passagell)around the oven. Bctwccn the stationery oven 9 and tho :lirc box 1 2rwater coil ll. is positioned, the upper end thereof being in contiguousrelation to the back Wltll ol the firebox l. The coil 11 is locatedbetween partition wells 12- cnd 11 which cxtcml verend.

tically within the body of the stove. The partition wall 12 assists insupporting the shelf 6 and also supports the back wall or casting 4 ofthe fire box. The Wftll 12 is provided with an opening 12 at its upperings being provided in the pr zscnt instance,

and two of said openings are located directly over the the box 1. it isof course understood that all of theseopenings are intended to becovered whenever.desired, with the usual removable lids. The top of thecloset or rcceptccle 7 is also provided with burner openings 14, thatare, as shown, of the design usually employed in stoves. At the back ofthe main portion of the stove is secured n cylindrical howl 15 \i'hichis intended to contain a wster boiler or heater l6 and which is providcdwith an upward extension 17 designed for attachment to the smoke pipe orline. The interior of the cylindrical hood 15 communicates with one endof the passage 10 by means of an elbow or Slll'lllztl pipe connection18, and a dzunpcr l9 governs said communication. B y means of this d:unpcr a draft may be established between the outer or upper end of theflue passage 10 and the interior of the hood. The szrid draft may be cutoil whenever desired. in addition. to the elbow 18, direct communicctionmay be established between the interior oi the hood and the maininterior portion ol the stove, by means of openings 2-0, each of whichis controlled by a. dmnper 21.

in addition to tho lire box 1, the stove cmbodies other healing devices.Those 11 citing devices are gesburners, and as illustrated there are twoof such burners, designated :22, provided for the opcuings ll of thecloset or wrccptaclc 7 and undcrnculli said gas burners 2'3is located a.soot tray 23 which is intcndcd to slide into the closet upon ledges 24through a side opening in the sold l'cccptzlclc 7. \Ybencvcr necessarythe tray 2b lmty be withdrawn laterally and cleaned. (lusburucrs arealso prov idcd for the burner penings l3 in the body ol the stove.'llrcsc last named gas burners arc designated 25 and .26. T110 burners25 are czu'ricd on the outer ends 01'' tubcs 27 that arc lillcd totelescope over the stuiloum' branch pipes 28 radiating from a. commonbond 2!). 'lnc burners 26 are carried in u stationary uumncr on the twocomplements-l brunch tubes 28. The head 29 supplies all the burners 25and 26 and is provided with an air inlet tube 30 that preferably entersthe front of the stove, the gas and air being thereby mixed to producethe proper blue flame. The water coil 11 is also supplied with a gasburner 31, and a gas burner 32 is located underneath the stationary oven9. I

The partition wall 12 nearits lower end is provided with an openingwhich is governed by means of a damper 33 preferably operable from thefront portion of the stove, and the said damper is also designed tocontrol one end of the flue passage 10. As illustrated in the drawings,the parts are so related that the damper 33 may either be swung down toclose the opening in the partition wall 12 or may be swung up into ahorizontal position against the lower left-hand corner of the sta- 2oti'onary oven 9 to extend entirely across and cut off the flue passage10. i From the foregoing description in connec tion with theaccompanying drawings it is evident that my im roved cooking stove mayutilize either coa' or gas or both as fuel. If it be desired to use coalalone, and atthe same time to heat the water coil 11, the oven 9, andthe boiler 16, the dam ers 21 may be closed, the damper 33 dropper andthe damper 19 left open. A draft will thus be estabished around theupper end of the water coil, down through theadjacent portion of theflue assage 10 to heat the coil, across the bottom of the oven to heatthe latter, and up through the other side of the flue passage past thedamper 19 and through the elbow 18 into the ,hood where it will heat theboiler 16 and finally pass up into the flue. When coal alone is used,the burners may be slid laterally out of the way where they will notproject underneath their respective burner opening's 13. It is to beunderstood in this description, that while the heat passes down aroundthe coils 11, it may pass through the coils by ,opening damper 33,although the coils are 1 primarily intended to be heated by gas suppliedthrough the burner 31. If it be desired to use both coal and gas, it isobvious that this can be done by burning'gas at any or all of theburners 22, 26, 31 and 32, the burners 2 5 being pushed back out of theway.

If it be desired to use only gas, the burners 25 are preferably drawnoutwardly into proper registry wlth the burner openings 13 and any ofthe gas burners before described, lighted, according to the particularconditions existing and the particular cooking operations desired to beperformed. For instance, the' burners 25, and 26 may all be lighted tocbok upon the burner openings 13, ,and the boiler 16 may be heated atthe same time by opening the dampers 21, or water may be heated bylighting the burner 31. 6; The stationary oven may be utilized by 'forthfor either coal or gas, wnich tionary sid'eration.

lighting the burner 32, or by lighting burners 22 the removable oven 8may be u a. ized, or both of said ovens may be used when, evernecessary.

When gas alone is used and the ,1 is lighted, the damper 33 may beturned a horizontal position across the flue passage 10 in which event adraft will be established in a downward direction between the partitionwalls 12 and 12, through the opening in a 5 the latter, and alongthe bottom at th oven 9 and up the outerisid'e t and finally through theelbow 18 into 15, the heat finally escaping through t.= connection 17And the coil 11 may heated when using coal as fuel, if the f 33 beturned upwardly againstthe an corner of the oven 9, for in this event,upper end of the coil is open the products combustion will ass downwai1y 1: r v the coil between t e partition 12 thence out past he damper 33a d the oven 10 and through the damper being understood that the latteris c It will be seen that I have pro-vial proved construction of cookingembodies in the one article a useful eon, tions of parts that arecorrelated in t action so that the stove may be all the'varyingconditions arising with a vice of this nature.

The same stove may be used sideratum, especially in flats or Phouseswhere the utilization of space Whenever it is n" .r shut off thegas for the purpose o the like, the fire box may be used It is to beunderstood that th 11 is intended to heat water for pur oses and it mayalso be used 9 device for hot water or steam hea terns.
